1. Show that if
2. Suppose that we know a noninteger maximum flow in a directed network with integer arc capacities. Suggest an algorithm for converting this flow into an integer maximum flow. What is the running time of your algorithm? (Hint: Send flows along cycles.)
derive an equation that can be integrated to find the angular velocity of the bar as it passes through the vertical
Find a technical journal for your current or planned field of work, and look for an article that has graphs, charts, or tables in it. Select two of the graphic presentations and represent them in a different format. (If something is presented as a..
a steam engine consists of a boiler connected to a turbine. the boiler tank has a volume of 100 l and initially
Write a mat lab code to calculate and plot the second explosion limit (2k1=k9[m] for the H2- air mixture with Phi=0.5 within temperature range of 500-1000k compare the line with the explosion limit in the textbook and see if they qualitatively agree...
In question 9.12, how much would profit increase if the materials costs are reduced by $200,000?
A house is maintained at 1 atm and 24 C and warm air inside a house is forced to leave the house at a rate of 150 m^3/h as a result of outdoor air at 5C infiltrating into the house through the cracks. Determine the rate of net energy loss of th..
Steam flows through a turbine. The inlet stream is at 1200 KPa and 290 C. The pressure at the exit is 75 KPa. A) Determine the quality and temperature of the steam at the exit. B) Determine the specific work produced by the turbine.
air is compressed by a 30-kw compressor from p1 to p2. the air temperature is maintained constant at 25-degrees celsius
Find the natural frequencies of the water tank considered in Problem 12.22 (Fig. 12.28) using a one-beam element idealization.
Methane gas in a piston-cylinder assembly goes under an adiabatic (no heat transfer) quasi- equilibrium compression. (This process is called isentropic process). The pressure and volume of the gas during the process are related as PV 1.3=constant.
Find (a) the angular acceleration, (b) the time taken for the speed to increase, (c) the work done, (d) the average power developed, (e) the maximum power developed.
a refrigeration cycle uses refrigerant 134-a as the working fluid. the refrigerant leaves the evaporator as a saturated
